I am putting a wiring harness in my 28 coach right now. under the hood and dash it was in perfect shape, but like most originals, it was totally shot from the front seat back although the conduit is still almost mint. All I can say is better safe than sorry. My 28 1 ton came from western Nebraska and is like a time capsule. It was also used to haul wheat and the engine pans and the tool box are still full of wheat chaff. That stuff really blows in the wind when the thresher is running. The wiring on that truck is nice up front also but has bad places going to the rear. Hate to replace the mostly original, but!!! sure hate to have a sooted up relic after the fire happens. I may save the old harnesses just to show anyone who may care in the future but since Dad was a fireman, well, you know.
